We had a wonderful two night stay at TT's property. TT arranged for an airport transfer which was appreciated after a 20 hour flight. The cost of this was 600 baht. She met us at the apartment and took the time to show us around the neighbourhood.
The restaurant below the apartment is run by her grandmother and the authentic Thai food was delicious! There are a number of great food options within a 5 minute walk. TT's information binder was extremely helpful in showing the location of these restaurants plus information about nearby attractions.
You can walk to Wat Arun in about 10 minutes and the port to catch the ferry across to the other side of the river is right there too. The cost is 5 baht per person and it is only a 2 minute ride. You get off right near the Grand Palace and Wat Pho.
We also visited a local market called Wanglang. It was about a 15 minute walk and had amazing, really cheap, local street food options. There is a 711 within a 5 minute walk as well.
We would highly recommend TT's place. The location in an authentic Thai neighbourhood was a really special experience. We were sad that we were only able to stay 2 nights.
